Alex Hasell Posted June 29, 2008 Author Share Posted June 29, 2008 Eric,I dont think you understand me Eric i am comfortable with the whole starting process i have it off by hart and yes your post is very usefull but thats not my concern i want to know what is best to do once you have flooded an engine? and secondly and more importantly i know that the tank should be level through its centre with the needle my question what if its not? what are the effects of it and why? You see i have just built my trainer and obviously things like tank and engine height are predetermined and there is no way that the height of the tank is any way near where it should be in relation to the needle valve hence my question.Regards, Alex Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 29, 2008 Share Posted June 29, 2008 flooded? - turn the engine on its side ( exhaust port down ) and turn the prop back and forth to clear the excess fuel. tank too high - possible floodingtank too low - possible insufficient fuel flow at some throttle setttings.

Andy Green Posted June 30, 2008 Share Posted June 30, 2008 Hi AlexYou say in your opening post that you are using a fuel pump, are you referring to the filling pump, or do you have an on board fuel pump?Andy Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 30, 2008 Share Posted June 30, 2008 he means the "filling pump" Quote Link to comment Share on other sites More sharing options...
Alan B Posted June 30, 2008 Share Posted June 30, 2008 Hi AlexWhen filling your tank - close your needle valve fully. When you are ready to start the engine then open it to your recommended running settings. Al Quote Link to comment Share on other sites More sharing options...
YakMad Posted June 30, 2008 Share Posted June 30, 2008 Just take the pressure feed (pipe going to silencer) off next time you are filling the tank, excess fuel will then not be pumped into the silencer, replace before starting and make sure that the vent tube inside the tank is pointing up.

Alex Hasell Posted July 2, 2008 Author Share Posted July 2, 2008 Ahaa Myron i think its because he's worked out i'm a petrol head (or Glow head) and as im just starting out i dont want to have to worry about all the calcs and things needed for lecy flying. Although i do see the appeal of it and in due time i fully intend on adding some elecy planes to my "hanger"Back onto topic for a min though i am some what puzzled as to why the manufacturer in this case Seagull who i belive to be one of the better ones have apparently given no consideration to what would seem to me to be one of the basics of setting up the airframe. In that the fuel tank is completely encased in the airframe which is good in that it cant move but leaves the carb/needle well above the centre line of the tank in this case it is actually above the top of the tank this cant be a good thing surely?? so now apart from some major surgery to the airframe i cant see how it can be rectified, but then another part of me says they must of sold plenty of these kits and if this was a major problem then they would surely of done some thing about it would they not! Any thoughts on this guy's would be welcome.Regards, Alex Quote Link to comment Share on other sites More sharing options...

Alex Hasell Posted July 3, 2008 Author Share Posted July 3, 2008 Eric ,That was my thought as well really i couldn't see how it could be to critical in this particular model either to be honest and yes its a pressureised system (3 pipe) thankfully i might add as when i came to run the engine in, nice post bye the way . Not for love nor money could i get it to start for hours i tried and went through 2 glow plugs!! now i realise it was simply because i wasn't getting enough mix in the engine just wasn't priming properly that and also a lack of experience of the "feel" of compression on such an engine all contributed to a very dejected me However on the second attempt a good blow into the muffler line did the trick alright i know this is not the best course of action cause it can introduce moisture but hey when needs must!Any way the result is i now have a fine running 46 for my lady and i'm sure they will get along fine Rgaerds and thanks for the reply, Alex Quote Link to comment Share on other sites More sharing options...
Alan B Posted July 4, 2008 Share Posted July 4, 2008 Hi AlexIf it is an SC 46 engine. they can be a pig at first to start if not set up right. All you need to do with these engines is to have the secondary /idle mixture set right. Finger over the carb air intake and a couple of turns on the prop to draw the fuel into the carb. About 1 and 1/4 turns on the main needle valve (they dont need much on SC engines ) as anymore and they tend to flood. They will then not normally miss a beat!Al Quote Link to comment Share on other sites More sharing options...
